Timesys is our development partner for Linux on Quartz, our latest SOM based on the Freescale Vybrid processor. They have been working with Freescale since the start of the Vybrid project so we think they qualify as experts on all things Vybrid.
The main tool set provided with Quartz is the LinuxLink PRO edition suite. This is usually US$5,000, but is free for Quartz development. LinuxLink PRO is a suite of tools for both platform and application development.
The best place to get started is the Quartz Development Center page on the Timesys site. This has links to download code and tools along with demos, documentation and getting started videos.
